Real Code

Real Code is a real-time collaborative coding platform that allows developers to create private coding rooms, share a unique room ID, and work together seamlessly. Whether for pair programming, technical interviews, teaching, or brainstorming ideas, Real Code provides an efficient way to write, edit, and share code with others instantly.

This project is designed to simplify remote collaboration by leveraging WebSockets to ensure smooth, real-time code synchronization across multiple users.

Tech Stack

• Frontend: React (for a dynamic and responsive UI)
• Backend: Node.js, Express (handling user connections and room management)
• Real-time Communication: WebSockets, Socket.io (for instant code updates)

Key Features

• Create Private Coding Rooms – Users can generate a unique room ID and share it with others.
• Real-time Code Synchronization – Code updates are instantly reflected across all connected users.
• Multi-user Collaboration – Supports multiple developers working in the same room.
• Minimal Latency – WebSockets ensure fast and efficient data transmission.
• Simple & Clean UI – A distraction-free coding environment with an intuitive interface.
• Room Persistence – Rooms remain active as long as users are connected.

Challenges & Solutions

• Ensuring Real-time Synchronization:
  Maintaining a smooth real-time experience was crucial. By using Socket.io, I implemented an efficient event-driven architecture to sync code changes with minimal delay.
• Handling Multiple Active Rooms:
  Managing multiple coding sessions simultaneously required an optimized backend. I implemented a room-based architecture where each session runs independently, ensuring seamless performance.
• Scalability & Performance:
  To support multiple users editing code at the same time, I optimized the WebSocket connections and minimized unnecessary re-renders in React, ensuring a smooth experience even with large amounts of data being shared.

Use Cases

• Pair Programming – Work with another developer in real time.
• Live Coding Interviews – Conduct remote technical interviews with shared code editing.
• Teaching & Mentoring – Instructors can demonstrate coding concepts interactively.
• Brainstorming & Debugging – Collaborate on fixing bugs or experimenting with code.
